IMPROVEMENT IN CAR-AXLE BOXES.

Specification folining part of Letters Patent No. 212,756, dated February 25, 1879 application filed July 27, 1878.

To all whom t may concern:

Be it known that I, JOSEPH NOTTINGHAM SMITH, of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Axlefollowing is a specification, reference being had to the accompanying drawings, forming a part of the same.

This invention relates in part to the construction and arrangement of the boX-hous ing and its adaptation to the sa'ddle, and in part to the oiling apparatus whereby the journal is lubricated, all of which will be more fully and definitely hereinafter set forth.

In the drawings, Figure 1 is a side view of the axle-box, showing it in position on the journal. Fig. 2 is a vertical midsection of the same, taken in a plane parallel with the axle-journal. Fig. 3 is an end or front elevation ofthe box. Fig. 4 is a transverse section of the boxl and journal, taken in the plane of the line a: in Fig. 2. Fig. 5 is a plan of the bottom of the boX and saddle. Fig. 6 is a sectional view of the saddle. Figs. 7, 8, 9, and 10 are detached elevation and sectional views of the oiling apparatus. Figs. 11, 12, I3 are, respectively, a sectional view and plan views of the cap which rests upon the journal.

The box is herein shown as adapte-d to skeleton trucks; but many ofthe novel features are as well adapted to be used in pedestals of special or common forms.

A is the saddle, which is provided with bored or tubular lugs to receive bolts which secure it between the straps of the truss. The lower lugs of the saddle are recessed to receive lugs a e cast on the housing B, while a spherical segment, b, on the latter rests in a corresponding concave or hollow in the roofplate of the saddle.

A balland socket support is shown in a former patent granted to me, and I make no broad claim to it here; but in that case the ball was cast with and formed a part of the housing. This construction is objectionable, inasmuch as the ball should be chilled to adapt it to the end in view, and this, from the unequal strains produced, hazards the integrity of the housing.

In my present invention the spherical segment b is cast separately, of chilled iron, and adapted to lit in a recess or socket inthe roof of the housing. It is attached by means of a wire staple, preferably cast in the segment, the ends of which pass through holes in the roof of the housing, where they are clinched on the inside. The lugs a a, on the lower edge of the housing, do not lit snugly into the recesses in the saddle, but have considerable play, as indicated on Fig. 5, so as to permit a moderate degree of lateral swing to the car. They serve, however, to check too much movement.

The stopping-bar C, which is hollowed to receive the vibrating oil-pump shown in a former patent granted to, me, rests between lugs at the bottom of the housing, and the upper corner engages a notch or recess, c, in the door D of the same. To add further 'support to the stopping-bar, it is provided with a lug at the back, which bears against the bev. eled front of the housing, just below the door opening. The bar is prevented from moving in the other direction by the cap E, which is interposed between it and a shoulder formed in the roof of the housing, and by the upper end of the bar resting against lugs on the side walls. The door D is hinged above at d, and is provided with a catch, e, on its inner face, which engages, when the door is shut, a springhook, f, pivoted preferably to the stopping bar. A groove at g in the edge ofthe opening below the door permits the insertion of a slender rod, by which the hook may be lifted and the door released.

Improvements in the oil-pump relate, chiefly, to the lower valve in the chambered stop ping-bar, and to the method of securing a bottom to said chamber.

Referring to Figs. 9 and 10, it will be seen that the chamber is enlarged for the reception of the valve h.

The bottom f is a plate with a central open ing and grooves across its under side. These latter serve to admit oil from the well to the pump-chamber, and to receive the fastening wires 7' j. These wires extend across the plate, and are secured by wrapping around pins or lugs on the sides of the chamber, as indicated in Figs. 7, 8, and 10.

The valve lo is a disk, which its somewhat loosely into the enlarged chamber, the shoulder formed by the enlargement limiting its lift. This valve has a hub or boss and holes or apertures in its thinned margin around the boss, (see Fig. 10,) which do not coincide, when the valve is seated, with the aperture in the plate i; but when the valve is lifted the oilmay pass up through both, as well as around the valve.

Referring to Figs. 11,12, and 13, the two latter show, respectively, the upper and under sides of the bearing-cap E, which rests upon the journal.

In the shell of the cap is formed a recess, 7c, into which the oil from the pump falls. From this eXtends a channel or channels, Z, which lead the oil to openings m, which communicate with a channel or channels, n, in the lining of the bearing. These channels are arranged in the ilanks ot' cap, and not in the crown, and they open out at the end of the cap adjacent to the stopping-bar C.

By this arrangement the oil is first delivered to the journal at the inner or back end, and thence finds its way to the front again.

At o is a notch or outlet from the recess 7c, which permits some portion of the oil to iind its way down the groove p in the stoppin g-bar, (see Fig. 7,) and onto the face of the axle-button. Should any oil escape from the recess or channels in the cap, it will nd its way into an overlowchannel, @1,-which will lead it to the front.

The head of the vibrating pump is housed on three sides by the chambered stoppin g-bar C, and its nozzle or spout vibrates between two adjacent lugs on the side walls. This prevents the oil from splashing and flying back of the' pump, and insures the spray all re-enterin g the pump.

The spout is arranged to direct the jet forward, so as to spatter as little as possible.

F is a lever-shoe, the inner end of which catches underneath a flange on a dust-excluding half-collar, G, in such a manner as to keep the latter snugly pressed against the re-enforce on the axle.

The outer or front end of the shoe is adapted to engage the beveled front of the housing, so as to drive the shoe to the back, and thus keep the collar G pressed closely against the back wall of the housing.

By reference to Fig. S, it will be seen that the nose of the shoe is rounded and fitted to engage the hollowed llllet 011 the collar. This collar is adapted to catch and return to the well such oil as may be thrown or collect up on the re-enforee.

The shoe F is hoilowed out and provided with an overhanging lip, r. The purpose of this is to catch, dellect, and throw back the oil to the well should it be driven inward by the lateral surging of the car.

The upward play of the front end of the shoe is limited by a suitable stop or shoulder on the bar (1 For this purpose I provide an adjustable pin, s,"`suitably secured in a hole or cavity in the shoe, the upper end of which abuts against a shoulder, t, on the stopping-bar when the outer end of the shoe is raised. This pin may be screw-threaded, or it may be secured in place by a set-screw, or in any other good or convenient way.

In addition to the collar G, I contemplate using a dust-excluding device located outside of the housing, similar to one described in a former patent granted to me.

H H are the bars or straps of the truss. I is the car-axle, and J J represent the wheels.
